Abstract

The invention belongs to the technical field of genetic resource sample libraries, and particularly relates to an ultralow-temperature human genetic resource sample library. The ultralow-temperature human genetic resource sample library comprises a library body, a motor is installed above the library body, a fan is connected to the tail end of a lengthened shaft of the motor, fan blades of the fan are located in the library body, at least one access door is arranged on the front part of the library body, a goods shelf is arranged in the library body, a liquid nitrogen atomizing nozzle is formed in the library body, the liquid nitrogen atomizing nozzle is connected with an outdoor liquid nitrogen large tank through a stainless steel vacuum liquid nitrogen pipe, and an electromagnetic valve is arranged on the stainless steel vacuum liquid nitrogen pipe. According to the ultralow-temperature human genetic resource sample library, the cooling effect of a refrigeration house is improved, liquid nitrogen is used as a cold source, the cooling effect is good, energy is saved, and the storage amount is large.

Description

technical field [0001] The invention belongs to the technical field of genetic resource sample banks, in particular to an ultra-low temperature human genetic resource sample bank. Background technique [0002] Existing Technology and Defects: [0003] Generally, for the quick freezing and storage of food, the temperature is ≤-50℃, which basically meets the needs; the storage temperature between -70℃~-80℃ is mostly used for the storage of medical samples, reagents, and blood preparations. [0004] At present, there are only liquid nitrogen quick freezers and small liquid nitrogen cryotherapy devices on the market that use liquid nitrogen as a cold source. [0005] Most of the well-known cold storages, refrigerators, freezers, etc. generally use Freon as a refrigerant, and a refrigeration cycle system is composed of a compressor, a condenser, an evaporator, a throttling device, and the like. In addition to some advantages, it also has some disadvantages, such as high power c...
